These modern cat’s-eye frames are made from bio-acetates, which are made using fibres in wood pulp and are actually biodegradable, as opposed to the common material acetate, which is made of petroleum origins (and lasts forever). 

We’re not the first super-fans to say this, but you honestly cannot tell Stella’s pieces are not real leather. And these alternatives, made from recycled polyester, don’t just look and feel good – they’re also better for the environment, reportedly creating 24 times less of an environmental impact.

This is one of those iconic wardrobe staples you’ll pass onto your daughters (or nieces). Even better, it’s made with 100% organic cotton. That’s important because conventional cotton farming requires toxic pesticides and fertilisers, and is also water-intensive. It can take 20,000 litres of water to produce 1kg of cotton (which is a single T-shirt and pair of jeans).

Worn by Amal Clooney to the Duke and Duchess of Sussex’s wedding, we love the vintage-inspired silhouette – and that the viscose in the fabric blend comes from 100% traceable and sustainable sources.

Stella McCartney also avoids production processes that do harm, so there’s no sandblasting used on any of her denim styles – a common technique that’s harmful to workers due to the exposure to toxic silica dust in the air. 

You don’t need to be vegetarian to consider a switch to faux: we learnt from Stella McCartney that in the Amazon, around 17% of the forest has been lost in the past 50 years, mostly due to forest conversion for cattle ranching (in part, so we can consume leather goods).

The tailoring is impeccable – and the fabric is too. This was news to us: viscose (or rayon) starts its life as a tree. And because it’s used to make so many clothes, every year 150 million trees are cut down to create fabric. Since 2017, all of Stella’s ready-to-wear viscose comes from sustainably managed and certified forests in Sweden.

Wool is one of the most naturally technical materials in the world – it keeps you warm, but it also breathes. Plus it has antibacterial properties and is long-lasting. Stella McCartney worked with a key knitwear supplier to avoid pesticides, detergents, processing chemicals and dyes, so the wool is sustainably produced and naturally biodegradable.

As a lifelong vegetarian, Stella doesn’t use any fur or leather in her designs, and these are the first ever vegetarian-leather Stan Smith sneakers.
